. vThis invention relates to .that `class of lhoists which are employedfor lifting ash barrels and other kinds of materials through4 fromv the basement or cellarto the sidewalk; or street 'on an areawa of a building Y theexteriorof the same.

It is the object of this invention pro-1 vide an operating mechanism fora hoist ofthis character which is simplein construction, efficient inl operation kand capable of being easily manipulated foreither raising or lowering the load without liability of getting out offorder. Y

In the accompanying drawings :-v f

The numeral-10 'represents anY areawayV similar kto ythose usuallyk placed adj acentV to vthe-outer sides of ,buildings for the purpose of providing a passageway through which j.

ash barrels, freight and-the like may be lifted from the cellar or basement of the'V building to thef-si-dewalk or street. This areaway is usually Vclosed at the topA when', ,not in use by ymeans-of .a movable cover ory door 11 which'may be mounted in anyv suit-.-

able manner.

VWithin this areawayA and 'on oneside'v .thereof is arranged the hoist which embodies my invention.- Thisrhoist'in its general `organization comprises a lower mast section y12 which is stationary,and ari-upper mast 'Y section 13 which is movable vertically on v the lower mast section, meansjfor, raising and lowering thefupper mast section' relativeto the lower mast section an'd-avdrum andl operating mechanism thereforfmounted on thel upper endo'f-the upper `mast section@ j section.

wardly while their `rear flanges 19 are in line and project. laterally into engagement with the guideways 17 yofthe lower mast The lower end of the lower mast ksection is preferably connected witha foot 20 which is in turn connected with the bottom or iioor of the areaway, and the upper end of the lower mast section is connected by a bracket 21 `with the'adjacent partfof the lwall of the areaway, as shown in Fig.` 1.

In this manner -the uppermast section is guided in its vertical movements on the during such movements. Upon thel upper end of the upper mast section are mountedthe lifting means whereby the removal vofthe load from' the cellar throughfthe rareaway lto the exterior of the building: may bev effected. Vmeans comprise a hoisting drum 22 upon the surface -of which a hoisting line 23iswound These lifting and unwound'for the purposeof raising and lowering the load whichA latter .may be at-V vvtachedto thisxline inV any suitable manner QrinStance by means ofva hookV 24. This drum is mounted on a shaft. 25 `which latter in turn. is journaled on a supporting arm 26 which is mounted on the upper mast section. Rotation ofthe drum is eifected by means of a crank shaft 27 journale-d on the yarm. 26 and provided .on one-end thereof witha crank 28, and a pinion 29 arranged on theiopposite end ofthe crank shaft and lmeshing. with a gear wheelSO'on the drum supporting arm 26..to b e either projected from the upperinast sectionor swung` yback kagain to .the mastin order to reduce the ob struction in Vth-e spaceinthe areaway the `supporting -arm. 26 is pivoted by means of `an upright pini31, and a. supporting block 32 on the upper part Vofthe upper section.

and having a crank, an upright intermediate shaft journalecl on the lower mast section, an upper pair of intermeshing bevel' gear wheels connect-ing the upper end of Said i11-V termecliate shaft with said upper horizontal shaft, and a lower pair of intermeshing bevel gear wheels connecting the lower end of said intermediate shaft with said lower horizontal shaft,'said upper horizontal shaft being arranged in rear of said lowermost Seo- 10 Y tion and lat right angles to said lower horizontal shaft. In testimony whereof I aiX my Signature.
